Experimental investigation of the shear mechanical behavior of sandstone under unloading normal stress

Excavations in rocks always induce unloading of stress in excavation-disturbed zones. In many cases, rocks fail due to shear under unloading normal stress. To study the shear mechanical behavior of sandstone under unloading normal stress, a new loading path was proposed, and direct shear tests under...
